John Deere Power Systems (JDPS) extended its generator drive power solutions with the introduction of four PowerTech prime power generator drive engines at INTERMAT in Paris. The new engines meet Final Tier 4 emissions regulations without the need for a diesel particulate filter (DPF) – giving OEMs with space-constrained installations more options.
The engines utilize a John Deere Integrated Emissions Control system equipped with cooled exhaust gas recirculation, a diesel oxidation catalyst and a selective catalytic reduction system, and join a lineup of Final Tier 4 generator drive engines that use the same technologies plus a DPF.
“We’ve been able to develop constant speed engines that do not require a [DPF] to meet both stringent emissions regulations and the performance our customers have come to expect,” said Darrin Treptow, manager, worldwide marketing for JDPS.
Product enhancements including increased power, low idle speeds, dual frequency ratings and easy paralleling enhance customer performance for prime markets. Low idle speed capability reduces fluid consumption and decreases wear on the engine during transport or start-up and shutdown checks. Electronic controls enable easy synchronization when operating generator sets in parallel, while offering flexible dual frequency operations of 50 Hz at 1500 rpm or 60 Hz at 1800 rpm. In addition to generator sets, these engines can provide power to selected constant speed applications.
New PowerTech generator drive engine models and power ratings include:
- PowerTech PSL 4.5L: 128 kWm.
- PowerTech PVL 6.8L: 160 kWm and 192 kWm.
- PowerTech PSL 6.8L: 216 kWm and 240 kWm.
- PowerTech PSL 9.0L: 273 kWm, 326 kWm and 345 kWm.
John Deere plans to begin production of the PowerTech PSL 4.5L generator drive engine in late 2015 while the PowerTech PVL 6.8L, PSL 6.8L and 9.0L generator drive engines will enter production in 2016.
